The detection method of toxic and harmful substances in electronic products (hereinafter referred to as the test method, the standard number of SJ/T 11365-11365) of harmful elements in RoHS requirements given the limited testing method. X-ray fluorescence spectrometry . RoHS directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. These six Hazardous materials are: Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent chromium (Cr6+), Polybrominated biphenyls (PBB), Polybrominated diphenylether. How It Works: Portable or benchtop XRF devices bombard materials with X-rays, measuring fluorescence to identify elemental composition (e. Results are quick—seconds to minutes. Applications: Ideal for initial screening of homogeneous materials (e., metals, plastics) in supply. Our range of analyzers for hazardous substance detection are designed to meet current directives such as RoHS, WEEE, ELV, EN71 and halogen-free, and have the flexibility to adapt to new directives as legislation evolves. X-Ray Fluorescence Analysis can be used as a pre-screening method for compliance since it focuses primarily on the parts of a product with the highest risk of containing RoHS substances and. XRF analyzers are used to determine the elemental makeup of tested materials, making them ideal for screening hazardous materials within electronics.
